Stuff like SIPs (structural insulated panels) and CLT (cross laminated timber) are kind of changing the game on prefabrication offsite for homes. The components are small enough for trucking but assembling each lego blocks onsite gets you far closer to a completed house per unit time compared to stick framing. I've even seen some smaller SIP houses that don't need a crane onsite. You also don't end up with the modular house stigma.
It's still a small % of houses built, but it's very cost effective and getting better (and more common)
